Foundations of Geography: Space, Place, and Patterns

Geography

The study of the Earth's landscapes, environments, and the relationships between people and their environments.

Spatial analysis

The technique applied to structures at the human scale, involving the geographic distribution of events.

Maps

Two-dimensional representations of Earth's three-dimensional surface.

Distortion

The alteration of the original shape or other characteristic of an object.

Reference Maps

Maps designed to show general information about places.

Political Maps

Maps that show human-made boundaries like countries, states, and cities.

Physical Maps

Maps that represent natural features such as mountains, rivers, and deserts.

Thematic Maps

Maps designed to focus on a specific theme or phenomenon.

Choropleth Map

A thematic map that uses colors or shades to represent data values.

Dot Density Map

A thematic map that uses dots to represent the volume or density of a feature.

Graduated Symbol Map

A thematic map that uses symbols of varying sizes to indicate quantities.

Isoline Map

A map that connects points of equal value with lines, such as in topographic maps.

Cartogram

A map that distorts land area sizes to represent statistical data.

Flow-line Map

A map that uses lines of varying thickness to show the direction and volume of movement.

Map Projections

Methods of representing the round Earth on flat maps, each causing different distortions.

Mercator Projection

A map projection that preserves direction but distorts size, especially near the poles.

Peters Projection

An equal-area map projection that preserves relative size but distorts shape.

Robinson Projection

A compromise projection that attempts to balance shape and area distortion.

GIS

Geographic Information Systems, a computer system that analyzes and displays geographic data.

GPS

Global Positioning System, used to determine absolute location on Earth.

Remote Sensing

The acquisition of data from Earth's surface without physical contact.

Census Data

Quantitative data that counts people and demographic information.

Qualitative Data

Information that describes feelings and qualities rather than quantities.

Absolute Location

The exact position of a place on Earth using a coordinate system.

Latitude

The measurement of a position north or south of the Equator.

Longitude

The measurement of a position east or west of the Prime Meridian.

Relative Location

Location of a place in relation to other locations.

Site

The physical characteristics of a location, such as climate and geography.

Situation

The location of a place relative to other places.

Arithmetic Density

The total number of people divided by total land area.

Physiological Density

The number of people per unit of arable land.

Agricultural Density

The number of farmers per unit of arable land.

Distance Decay

The principle that states that interaction decreases as distance increases.

Time-Space Compression

The phenomenon where technological advancements reduce perceived distances.

Environmental Determinism

The theory that the physical environment shapes human cultural development.

Possibilism

The theory that the environment sets limits and people can adapt accordingly.

Map Scale

The mathematical relationship between map distance and real-world distance.

Scale of Analysis

The level at which data is aggregated to identify patterns.

Formal Region

An area defined by one or more definitive characteristics.

Functional Region

An area defined by a central focus or node, with diminishing influence outward.

Vernacular Region

An area that people believe exists as part of their cultural identity.

Diffusion

The spread of a feature or trend from one place to another over time.

Relocation Diffusion

The spread of an idea through the physical movement of people.

Expansion Diffusion

The spread of a feature in a snowballing process.

Contagious Diffusion

Rapid and widespread diffusion throughout a population.

Hierarchical Diffusion

Spread of ideas from authority figures to other individuals.

Gravity Model

A mathematical model predicting levels of interaction based on population size and distance.
